Flight Stability And Automatic Control Nelson Solutions -
SM = (xcg - xnp) / c
Substituting the given values, we get:
-0.05 < 0
Therefore, the aircraft is longitudinally stable.
An aircraft has a static margin of 0.2 and a pitching moment coefficient of -0.05. Determine the aircraft's longitudinal stability. Flight Stability And Automatic Control Nelson Solutions
-0.2 > 0 (not satisfied)
Therefore, the aircraft is laterally stable. SM = (xcg - xnp) / c Substituting
where n is the yawing moment.
